Sanyo CRT-tv. HOT tested bad. Transformer noisy. What next?
Sanyo 35" CRT Mod # DS35590. PROBLEM: No pic or sound, only the steady, high-pitched whine. Not very loud. Only unplugging the set stops the noise. Power button ineffective. Used small tube-in-ear stethescope method to find sound - sound is from transformer nearby, for sure. This is NOT the FBT, it's the other... 8 Jul 2010 04:48

NAD 140 schematic please
Hello all, I'm in need of a schematic for a NAD 140 receiver. This is a very early NAD, likely around 1975, before they were sold in the USA, and before the 3020 integrated amp that made them famous. I'm hoping someone in the Canada or Europe may have some service info. There were 4 receivers in this se... 30 Jun 2010 16:29

MicroGem DTV converter gets pretty hot
I just bought a used MicroGem DTV converter at an auction. The price was right, and it works ok. But I noticed that it gets pretty hot compared to my other converters (other brands).

Danger of running hot receiver (Kyocera)?
Got someone with a Kyocera receiver (R-851, 85 w/chan.) that they say "smells like something's burning". Don't have more specific information than that; I'm assuming no magic smoke is visible. I'm advising them that perhaps something (dust, etc.) is in the heat sink that's getting heated and smelling. Apparent... 1 Jul 2010 20:05

So, who's the king of finding data sheets ... ?
I have a JVC hifi on my bench. Brand new, purchased by a British soldier from a base somewhere else - possibly an American one, I seem to recall being told. Oddly, for modern equipment, it has a voltage selector switch, which was of course set to 120v, when he applied 240v UK power to it ... The unit has a swi... 1 Jul 2010 21:10
